This is a much cheaper version of the foil sound deadeners and underlays we sell. This particular insulation is basically bubble wrap with two layers of foil on both sides.
Good for insulating headliners, floor pans, trunk areas, door panels, kick panels and just about anything else you might want to use it for. This insulation comes in a 48" X 72" roll. Just grab a pair of scissors and cut your shapes. You can use any adhesive you like (contact cement or weatherstrip adhesive, etc).
Again, this is a much cheaper way to go if you want to cut corners, but it's far from the quality of our correct underlays and sound deadeners.
